[Histological, electron microscopical and X-ray microanalytical findings in malakoplakia of the kidney (author's
Abstract:
Malakoplakia which was found in the kidney if a man aged 55 years is described. This rare granulomatous lesion was extirpated together with a renal cyst. So-called Hansemann-cells with inclusion bodies and ring structures were found by light and electronmicroscopic examinations. These concentrically arranged ring like structures were not typical Michaelis-Gutmann-bodies, and they consisted of microfibrils and small granula. Using X-ray microprobe analysis could be detected calcium. These findings were considered to be an early stage of malakoplakia.
Insights
This study describes a rare kidney malakoplakia case in a 55-year-old man. Findings suggest an early stage of this granulomatous lesion, characterized by unique cellular structures and calcium deposits.
Area of Science:
- Nephrology
- Pathology
- Histology
Background:
- Malakoplakia is a rare granulomatous disease.
- This case involves a 55-year-old male patient with kidney involvement.
Observation:
- A rare granulomatous lesion was found in the kidney, extirpated with a renal cyst.
- Light and electron microscopy revealed Hansemann-cells with inclusion bodies and ring structures.
- These structures were not typical Michaelis-Gutmann bodies.
Findings:
- The observed ring-like structures comprised microfibrils and small granules.
- X-ray microprobe analysis detected calcium within these structures.
- The findings are indicative of an early stage of malakoplakia.
Implications:
- This case expands the understanding of malakoplakia's early histopathological features.
- The identification of calcium suggests a potential role in lesion development.
- Further research may elucidate the pathogenesis of early-stage malakoplakia.
